| 中文摘要 | co2-in-water (c/w) emulsion was formed by using a nonionic surfactant of poly (ethylene oxide)-poly (propylene oxide)-poly (ethylene oxide) (p123), and palladium nanoparticles were synthesized in situ in the present work. the catalytic performance of pd nanoparticles in the c/w emulsion has been discussed for a selective hydrogenation of citral. much higher activity with a turnover frequency (tof) of 6313 h(-1) has been obtained in this unique c/w emulsion compared to that in the w/c microemulsion (tof, 23 h(-1)), since the reaction was taking place not only in the surfactant shell but also on the inner surface of the co2 core in the c/w emulsion. moreover, citronellal was obtained with a higher selectivity for that it was extracted to a supercritical carbon dioxide (scco(2)) phase as formed and thus its further hydrogenation was prohibited. the pd nanoparticles could be recycled several times and still retain the same selectivity, but it showed a little aggregation leading to a slight decrease in conversion. |
